Vosk Delta (noun): delta at the mouth of the Vosk River where it empties into the Tamber Gulf and the Thassa beyond, is a marshland thousands of square pasangs long, is treacherous and difficult to navigate, having channels that change almost overnight.  The marshes can be traversed in small rush crafts through hundreds of shallow, constantly shifting channels.  The treacherous delta is inhabited, particularly in the east, by communities of rence growers who eke out a living harvesting rence.  Often little more than a trackless marsh its poor visibility is due to the rence plants and its sluggish, muddy waters that vary from a few inches deep to deep enough for a ship; quicksand can be found there as well. The average depth, after the spring thaws upriver, is three to five feet and is infested with insects, snakes and tharlarion. It is the habitat of the marsh tharlarion and the predatory Ul.  Marsh sharks even swim among the reeds. The eastern portion has fresh water. Port Kar that lays some hundred pasangs from its northwest edge, bordering on the shallow Tamber Gulf, claims the delta. Ships from Thassa cannot pass through the delta to the Vosk River due to the delta’s almost impassibility.  The entire area is claimed by Port Kar which lies within it, some hundred pasangs from its northwestern edge.

The Vosk League, a political and protective alliance, was formed to promote trade interests by the towns along its banks.  Most towns on the river are free states and belong to the Vosk League. The southern bank is much less populous than the northern bank.  (See also “Vosk League”)  (Book 1:  Tarnsman of Gor, page 72) Vosk Sorp (noun): a giant clam that thrives in the seas and Marshes of Gor, the shell of which is large enough to be used as a throne.
